Free Open Graph (OG) Image Generator for AI
Summary
TwitterShots 2026.8.14 launches a Free Open Graph (OG) Image Generator for AI — create 1200×630 social preview images in the browser, or call the API from docs, launches, and AI agents.
What's new
Link previews look broken when every page shares the same default image. This tool generates a 1200×630 OG image from a title, template, and theme — then lets you download PNG or reuse the live API URL.
- Editorial, gradient-title, and OpenAI-style templates
- Color themes and image backgrounds
- Live preview before you export
- Free OG Image API for agents and automation
How to create an OG image
- Open OG Image Generator.
- Enter a title and pick a template (editorial, gradient, or OpenAI gradient).
- Choose a theme or background and check the 1200×630 preview.
- Download the PNG, or copy the
/api/og-imageURL for docs and agents.
